Spectral analysis of steel pipes
Spectral analysis of steel pipes
Spectral analysis of steel pipes is a method of identifying steel pipes and determining their chemical composition and relative content according to their spectra.
Spectral inspection is a kind of material analysis, and spectral analysis is one of the most common test methods to determine the chemical composition and content of steel pipe.
According to the analysis principle, spectral analysis can be divided into two types: emission spectrum analysis and absorption spectrum analysis.
Principles of spectral analysis
Emission spectrum analysis is based on the measured atom or molecule in the excited state of the emission of the characteristic spectrum intensity calculation.
Absorption spectroscopy is based on the characteristic spectra of the elements to be measured, through the sample vapor to be measured in the ground state atomic absorption spectrum of the elements to be measured after the intensity of the weakened calculation of its content.
Method
Firstly, the rust and other impurities on the surface of the steel pipe are ground off by a polishing machine, and then shot on the surface of the steel pipe by a spectral gun. The percentage of the chemical composition of the steel pipe is displayed on the display screen.
Advantages of spectral analysis
Spectral analysis is simple and accurate, and it is an indispensable and important analysis method for metal material inspection of power equipment.
